Hi @rebop -

Is this for bookmarks that you have imported or is this for bookmarks you are adding? Would you be able to open the browser console (ctrl + shift + j), monitor it while you add a new bookmark that fails to store the favicon and then post any relevant logs that appear in that time here?

[rebop]

This is for newly created bookmarks. Some, few, but consistent. They work in Classic, not G4.

Examples. Boobkmark and tab Classic:

G4:

Interesting here on debug. But Classic sees it?

No errors in Classic debug.

I believe this issue is caused by the default CORS policy being set to strict-origin-when-cross-origin, which is default for increased security when a website doesn't explicitly set a policy on requests being made from the site. It will work with Classic because setting strict-origin-when-cross-origin as the default referrer policy started around 2020/1. It's on the website to declare a different policy.

The preference network.http.referer.defaultPolicy can be changed to value 3 in about:config to match the default in Classic, no-referrer-when-downgrade. I cannot recommend that you do that as it will reduce the security of the browser, but if you are comfortable with the risk it should solve the issue. You can read more about referrer policies here.

Thanks. Tried changing to 3, restarting and it had no effect.
